Question

Maxwell equation cannot be derived from which of the following law?

• A. Biot savart law
• B. Newton's Law
• C. Planck's law
• D. Gauss's Law

Answer 1

Answer: (C)

Planck's law

Answer 2

Maxwell's equations are fundamental postulates of classical electromagnetism. They are not derivable from more basic principles within classical physics but rather unify existing empirical laws.

1. Gauss's Laws are directly part of Maxwell's equations.
2. Biot-Savart Law is a consequence of Ampere's Law, which is part of Maxwell's equations.
3. Newton's Laws describe classical mechanics, a distinct branch of physics from classical electromagnetism.
4. Planck's Law is a fundamental law of quantum mechanics, which describes a different physical regime (quantum) than Maxwell's classical equations. The classical framework of Maxwell's equations cannot be derived from a quantum law.
